It reads much more smoothly, now! Cute pink fish deserves crystal clean prose for swimming!
Only other thing I'm noticing is verb tense. You've started and mostly keep to present, which I like! Very fitting for an author avatar origin story.
There's a few places where you dip into past tense and don't need to:
"Occasionally, my owner would enter the room"
Should be "Occasionally, my owner enters the room"— same for the rest of this paragraph. You do switch back into present tense with, "He's a man of no words"
One day my owner decided to leave a little present
Should be "decides to leave".
There's a few other little things, but you didn't post this for critique, so I'll leave that be (unless you want feedback). It's a charming introduction!
